Construction mastic in Ashurst Bridge
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Cost factors for mastic packages
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- How accessible the joints are
- The site’s rules and procedures
- Phasing around occupants
- Quantities, in metres or numbers
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.
Sending details for a quote
However big the job, the same details help:
- How the joints are reached, and at what height
- Where the site is, with the postcode
- Whether the building will be occupied during the work
- Approximate linear metres or a joint schedule
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, ring 01277 525 020 or email the details over.
How we handle construction mastic in Ashurst Bridge
Mastic Doctor has been a subcontractor on construction projects for over 20 years. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. To price a package in Ashurst Bridge, send drawings and the specification through our quote form. We work on cladding and panel joints, floor and skirting junctions and sanitary and kitchen joints, and the usual reasons a site gets in touch are window and door perimeters that won’t pass inspection and perimeter gaps outside the sealant’s range. A specialist sealant contractor works differently from a general builder: in Ashurst Bridge, that means joint design, primers and backing rod as standard.
Construction in and around smaller places such as Ashurst Bridge is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Damage to finishes by other trades after we have sealed
- Specifying the product where the designer hasn’t
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly.
Joints and surfaces we work on
- Sanitary and kitchen joints
- Brick and block movement joints
- Internal decorators’ caulk
- Floor and skirting junctions
- Window and door perimeters
- Cladding and panel joints
What the job involves on each surface
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly, and any bath is loaded with water first where that’s the agreed method.
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted while moving joints need a flexible sealant.
After the work
A few simple habits keep the new joints working:
- Keep finished joints away from paint, plaster and scrapers
- Flag uneven or tapered frame gaps early
- Record the products used in the O&M file
- Share drawings and the specification as soon as possible
If a joint is damaged after sealing, flag it early. We can return to clear snags before handover, priced as part of the package or separately.
Snag items left to the last week put handover at risk. A planned close-out through each area as it completes keeps the list short and keeps handover on track.

What we need from you

Construction mastic around Ashurst Bridge: points for this area
Ashurst Bridge is within about 3 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. The area within 2 miles of Ashurst Bridge holds several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Extensions at sites like Tatchbury Mount Hospital (to the north-west of Ashurst Bridge) normally sit beside working departments, and the mastic follows strict access rules. For contractors on a campus like Southampton Solent University, which lies east of Ashurst Bridge, facade and perimeter sealing has to fit around students and term dates.
Ashurst Bridge is about 1 mile south-west of Totton, in Hampshire. Anywhere in SO40, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Hampshire coverage takes in 723 places, large and small.

Common problems we fix in Ashurst Bridge
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Most enquiries start with something like this:
- Perimeter gaps outside the sealant’s range
- Mastic snags holding up handover
- Inconsistent sealant finishes from plot to plot
- Cracks opening in caulked internal joints
When a school such as Hazel Wood Infant School is extended or refurbished, the mastic package is often squeezed into the holidays.
Questions to ask before you book
- How joint depth will be controlled
- The named product and why it was chosen
- Who will actually carry out the work
- How the joint faces will be prepared and primed
Ashurst Bridge: questions and answers
Does the sea air around Ashurst Bridge change the choice of sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is hospital work, at somewhere like Tatchbury Mount Hospital, something you do?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
Do you work in Ashurst Bridge?
Yes. Ashurst Bridge is in our area and the rest of Hampshire. For a quote, speak to us on 01277 525 020 or email drawings and photos.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
